Subject [jira] Created: (COUCHDB-857) no continuous replication with doc_ids param
Date Wed, 18 Aug 2010 12:45:16 GMT
no continuous replication with doc_ids param
--------------------------------------------

                 Key: COUCHDB-857
                 URL: https://issues.apache.org/jira/browse/COUCHDB-857
             Project: CouchDB
          Issue Type: Bug
    Affects Versions: 1.0.1, 1.0, 0.11.2, 0.11.1, 0.11.3, 1.0.2
            Reporter: Benoit Chesneau


I investigated more on this problem : 
http://markmail.org/message/bazjkhmwcrdp3kcf

I've found that that *continuous* replication isn't possible with "doc_ids" parameter. I confirmed
this reading the code :

    DocIds = couch_util:get_value(<<"doc_ids">>, PostProps, nil),
 
    ... snip ...

    case DocIds of
    List when is_list(List) ->
        % Fast replication using only a list of doc IDs to replicate.
        % Replication sessions, checkpoints and logs are not created
        % since the update sequence number of the source DB is not used
        % for determining which documents are copied into the target DB.
     
        ..... snip
    _ ->
        % Replication using the _changes API (DB sequence update numbers).


Why can't we have continuous replication with "doc_ids" ?
